From: Structure and tailspike glycosidase machinery of ORF212 from E. coli O157:H7 phage CBA120 (TSP3)
Intramolecular aromatic clustering in the catalytic domain of TSP3. (a) close-up of the larger cluster (cluster 1) comprising 12 aromatic amino acids (b) The two intramolecular clusters are highlighted as yellow spheres in the context of the entire trimer. An intermolecular threonine ladder and the preceding 3 His367 residues are also indicated.
